The repository specifies the MIT license.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Configure the documented Docker Compose services for Ollama and Ollama4J Web UI, then start them.

Create a docker-compose.yaml containing the Ollama service and the ollama4j-web-ui service.
Configure the UI service with OLLAMA_HOST_ADDR set to http://ollama:11434 and publish port 9090 to container port 8080.
Start the services with docker-compose -f /path/to/your/docker-compose.yaml up.
Open http://localhost:9090 in a browser.

The documented setup makes the web UI available at http://localhost:9090 and connects it to the Ollama service in the Compose configuration.

The repository says the project is no longer actively maintained and has migrated to Doota.
